Аннотация

Mathematical modelling of turbulent natural convection in a semi-open cavity with a heat-conducting walls of finite thickness with radiant heating of internal boundaries was performed. Two-dimensional problem of the conjugate heat transfer was solved by means of the finite difference method. Scale influence of open boundaries and radiant heating of the gas - wall interfaces on the formation of differential and integral heat transfer characteristics was established. An increase in the dimensionless time (τ) led to displacement of extremum temperatures in the typical cross section (Y = 0.5) to an open vertical boundary. The average Nusselt number monotonically increased at the gas - a wall interfaces in a range of 400<τ<1200.
